I have a VBA routine that that opens a template drawing and modifies and saves the drawing. The template Dimension Standard is "ANSI". After the drawing has been modified and saved the Dimension Standard is still "ANSI". However, after the drawing is closed and then reopened I get a dialog box that the drawing has one or more errors do I want to recover? If I say No then the drawing opens normally but the Dimension Standard is now "ISO" and I have no associated dimstyles. Changing the Dimension Standard to "ANSI" and saving eliminates the error. I'm at a loos to know what is causing this, It only happens with drawings that have been generated with the VBA routine.
